Analysis Of Plant Configuration And Ecological Function In Shanghai Residential Area

Space building is a very important impact for plant on the the environment of residential,a good plant landscape space will create a good living environment,plants also have ecological function,reasonable using plants to create a space,more conducive to play plant ecological function,improve and enhance people's living environment.By choosing three different quality in Shanghai area,high-grade villas,villas and high-rise residential areas,residential areas,the common life of three different living area of plant species and plant configuration status were investigated.On the basis of studying plant species and plant configuration,this paper studies the ecological function of plants,and mainly studies the ability of plants to cool and humidify,reduce noise and dust.Study of 6 kinds of common pathogens in the habitable zone of Shanghai plant Buxus megistophylla,Koelreuteria integrifoliola,Ginkgo biloba,Osmanthus fragrans,Pittosporum tobira,NandinaDomestica in plant leaves dust pH,EC value,and contains the content of heavy metal elements,using data analysis software SPSS and EXCEL software for statistical analysis.The results show that:1.Suitable for residential areas in Shanghai plant configuration mode: the upper configuration tall Cinnamomum camphora and Osmanthus fragrans,forming open canopy lines,soften the stiffness of the surrounding buildings,structures,Osmanthus fragrans in the autumn and winter,brings on the smell of experience,middle configuration Photinia×fraseri,bright-coloured red leaf has excellent ornamental,Rhododendron pulchrum,the lower the plant disposition also has the very good ornamental flowering.The plant landscape is distinct,seasonal change and excellent ornamental,integrity.2.The temperature in the area of the plant configuration than the temperature of the plant configuration area by an average of 3 ?,humidity increased by an average of 2.5% RH;The noise in the plant configuration area is at least 7dB lower than that in the no-plant configuration area;3.Among the six common plants in the Shanghai residential area,Koelreuteria integrifoliola has the most metal elements and the least metal elements of Pittosporum tobiras..The size of the capacity of the plant dust is from big to small: Koelreuteria integrifoliola > Osmanthus fragrans > Buxus megistophylla > Ginkgo biloba.> Nandina domestica.>Pittosporum tobira.To sum up,plant configuration is closely related to plant ecological function,and good plant configuration can make a good cooling and humidifying effect.In the residential area of Shanghai,it is possible to choose plants such as Koelreuteria integrifoliola,Osmanthus fragrans,Buxus megistophylla and so on.
